The invention also includes other minor included in the more which follows:

The specific features of invention dis closed and claimed herein may be embodied in either oi' the `two types oiJ lienter illusq tinted, the mein diiierences between 'the two heaters being` liot in the ense of the lire place beater lie casing; is inode to conform somewhat io the shape oi? the fire place in vwhich it is lo set und. elle mnuinenintion is confined eo the liront porion which :rione is presented eo the room, nliile in the onse of lie heater which is sdopized lo stand in the room like en ordinary soave the easing is of symmetrical fornmeion und more or loss ornnmenied on all sides, its iront pori-ion lion/ever, :is in the cose of VAelle lire place heater, being constructed to sin'iulnte :in open grate lire and with doors ziiording access eo certain portions of the heater.

The casing of both beaters is indicated by l and is of a. general rectangular shape, the width end elle height being approximately equal, While elle depth is eoiisiderubly less. 'llie Gesineo ments or chambers 2 and 3 respeceivelyi the former occupying the lower porion of the casing and lie leer elle upper port-ion, elle two chambers being seperzred s. liori- Yzornfll diopl regni The lower "empereinenil 2 is lie conibnsion ciiornb in which is located a. yburner consisting of s detailed description features which Will beA aluminum, extending laterallyv along the middle oit the chamlier, the pipe having a .row of burner openings or nipples along the top for the emission ot gas. This burner is to be connected with a gas service system by pipe. 6 which passes along the front and lower portion ot the heater and contains a regulating valve T and a supply valve 8 by which the l'low oit gas tothe burner is controlled. lt may be mentioned that the valve 7 is fixed in its adjustment to supply a constant quantity ot gas regardless ol the pressure in the syste-m, while the other valve 8 is used to modify the uniform pressure and supply as desired.

The upper compartment 3 is an open space serving as a heat closet through which the heated air and products et' combustion pass to the atmospln re, iu the meantime giving up heat to the walls ot the closet from which it is radiated into the room. T he `front wall of this heat closet ma)T be reticulated as indicated at 9 in Fig. 1, and is provided with doors 10 through which access'may be had to the closet for the purpose of introducing or removingl cooking; vessels. rl`he floor or' the heat closet, which is the diaphragm e, is provided at its .middle portion innnediatelyT baclr et the front doors, with an opening normally covered by a lid ll, While adjacent the lid and' toward each end of the diaphragm it is provided with a grating or series or per'forations 12, extending substantiall;T from front to rear or" the diaphragm. mmediately beneath the diaphragm there is provided a heating` struc ture 1S formed of sheet or cast metal and either integral with the diaphragm or attached thereto, this heating; structure being preferably duplicate, as shown, and arranged to the right and left of the middle portion ot the diaphragm where the lid 11 is located. Each oit these structures is provided with a passage 1-1 which opens at one end tothe combustion chamber 2 at a point near the middle and upper part thereof, thence runs tortuously back and forth and connects with a set ot the openings 12 in the diaphragm 'to establish communication between the ripper and lower chambers. As seen in Fig. 2 the passage vcrticalhir is shallow but in Width' is substantially equal to the depth or' lthe main casing the two structures covering the diaphragm except at its middle. These heating structures are lo cated directly above the burner so that they vbecome highli7 heated during the operation ot the device and are adapted to impart their heat to products olf combustion and air which are compelled to flow through the pa ssages in moving from the combustion chamber to the het closet. The entrance from the combustion chamber to the tortuous sages, oit the heating,` sti i :ture is placed ai Y jacent the upper middle portion oil the chamber because the circulating gases in the chamber converge at that region and unless carried away at once would burn and discolor the front wall of the casing. At the same time, the middle part of the diaphragm containing the lid is not shielded from the frame and is therefore heated sufliciently to enable light c )olring` to be done in a vessel placed upon the lid or over the lid opening.

Across the `bottoni of the combustion chamber is al diaphragm 15 "which for the most part is an imperi'orate plate. Along the middle directly beneathlhe burner pipe 5 this diaphragm is provided `with a .screen or a narrow field of perforations 16 which serves to equalize and direct the loivot air "from below into the combustion chamber. The perforated area being narrow and di rectly under the burner tube, compels all of the air that enters from belowT to pass upward on each side of the rod oit flames risinrr from the burner, thus stiliening the flame and promoting the combustion of 'the fuel. The air inlet at the base of the heater may have flue openings variously placed in the walls ot the heater below the level of the diaphragm 15.

ln this heater the fuel is burned Without preliminary mixing with air and the flames are therefore luminous, the light and heat therefrom being directed by a' reflector 17 through a grated and colored Window 18 simulating an' open grate fire.

ln the operation ofthe heater all of the air that enters the combustion chamber together with the products of combustion must pass through the tortuous passages of the heating structures 13 and in so going any fuel not fully consumed is brought into contact with the hot Walls of the structures 13 while in close association with the air and is fully consumed or converted by the time it passes into theI heating chamber or heat closet 3, through the openings 12. The tortuous passages are sulr'iciently restricted to slightly delay the flow of gas from the lower to the upper chamber to permit of the continued and complete combustion of the fuel. From the hot closet the heated gases pass to the outer atmosphere and a rapid circulation thereof is set up and maintained while the heater is in operation. Thel heating structure 13 with the tortuous passages not only serves to promote and complete the combustion ot the fuel, but also absorbs a. large amount' of heat radiated from the llames, which together Withthe heat absorbed by the Walls of the heater, converts the structure into an etlective heat radiating unit.
